SANITARY AND PROTECTIVE COVER FOR PERMANENT WAVE PADS Filed Dec. 22, 1954 ,JM 4,. @MCL.

Patented Apr. 28, 1936 UNITED STATES PATENT OFFICE SANITARY AND PROTECTIVE COVER FOR PERMANENT WAVE PADS 2 Claims.

Generically this invention relates to sanitary coverings, but is more especially directed to such a covering for insulation pads employed in connection with the giving of permanent waves to the hair.

Prior to attaching a persons hair to the instrument subsequently to be heated a felt pad is inserted intermediate the instrument and the scalp, that is, the tuft of hair to be waved is threaded through an opening in the pad which latter fits close to the scalp and protects the head from the heat. While these pads can be Washed, they seldom are, the usual custom being to use the pad repeatedly before being discarded. However, when the pad has been applied to an unhealthy scalp a subsequent washing does not always sterilize the pad sufliciently to destroy the bacteria, and, consequently, when the pad is again used the heat in connection with the waving operation may develop the organisms lurking therein to such an extent as to cause an infection of the scalp, and therefore the principal object of this invention is the provision of a multiple covering preventing contact of the pad with a persons head, whereby the outer layer of the covering may be discarded after each use of the pad so that a fresh sanitary surface is presented each time the pad is employed.

Another important object of this invention is the provision of a sanitary multiple covering substantially conforming to the shape of the pad comprising a plurality of attached layers of absorbent material such as paper, and the like, and formed with an opening corresponding to and registering with the opening in the pad whereby after each use the layer contacting the scalp may be detached and discarded thereby presenting a fresh sanitary surface for the next use which not only presents a new surface but maintains the pad in a clean and sanitary condition and renders said pad substantially indestructible.

Another object of this invention is the provision of a covering for the type of pad used for giving a croquignole wave presenting a multiplicity of layers on opposite sides of the pad so folded, slit and attached that the outer scalp contacting layer on one side or the outer layer on each side may be discarded after each use of the pad so that during its life the pad never comes in direct contact with a persons scalp, and at the same time presents through the medium of said cover a sanitary scalp contacting surface.

A further important object of this invention is the provision of a multiple sheet covering for certain types of pads such as the circular type used for giving a spiral wave formed with an opening registering with the opening in the pad and extending in one direction substantially beyond the edge thereof which not only presents a covering for the pad but protects the neck from the possibility of being burned when the hair has been released from the machine and the heated metal coverings hang loose before being detached.

Another important object of this invention is the provision of a replaceable covering for permanent wave pads having suitable openings conforming to and adapted to register with similar openings in the pads, comprising predeterminedly folded detachable superimposed layers, the exposed layer portion of which may be detached and discarded after each use so as to present a sanitary surface, said cover constituting an additional protective medium against burns by catching and absorbing such heated excess chemical or.liquid as may be liberated during the waving process.

With these and other objects in View, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several figures, of which:

Fig. 1 is a plan view of a blank folded upon it-' self, and formed to define the detachable sections prior to being applied to the pad.

Fig. 2 is a view of the blank illustrated in Fig. 1 partially folded showing the position of the pad.

Fig. 3 is a plan view of the cover as applied and showing the different layer sections.

Fig. 4 is a plan view of a different type cover and pad showing the layer sections.

.Fig. 5 is a cross sectional view of Fig. 4.

Heretofore the felt pads interposed between the scalp and the wave producing mediums, where used repeatedly, have proven unsanitary and attempts to effect their sterilization after each use have proven not only laborious but expensive by reducing the life of the pad, and it was, therefore, to overcome such disadvantages and to produce a multiple covering conforming substantially to the configuration of the respective types of pads used in connection with different types of waves, said covering being slightly larger in dimensions than the pads so that the thin, pliable edges of the covering would slip one over the edge of the other thereby substantially covering the scalp and giving more complete protection during the waving operation than the shorter felt pads alone could give, thereby tending to reduce insurance rates in connection with permanent wave operators and additionally presenting an unused surface each time the pad is employed without substantially increasing the production cost incident to the waving process, that I designed the sanitary and protective covers forming the subject matter of this invention.

In the illustrated embodiment characterizing this invention there is shown a rectangular shaped blank A constructed preferably of crepe paper or other suitable absorbent material folded upon itself as at to form two layers, each edge of the blank, in the present instance, being cut along the alternate diagonal lines 2 to define the foldable end sections 3 and intermediate sections 4, said sections being foldable on the lines 5 and Sand each of said sections being formed with a central longitudinal slit 1 adapted when the sections are folded to register with each other and with a simi lar slit 8 formed in felt pad B whichthe folded sections are adapted to cover, as will hereinafter more fully appear.

' The intermediate blanks 4-4'are folded upwardly upon themselves along the lines 6 and the sections 3 are folded downwardly or outwardly along the lines 5 in superimposed relation on the respective sections 4. The pad 9 is interposed between the intermediatellayers 4'-4 and the folded sections secured over said pad by a string adapted to be suitably tied or other suitable fastening element 10 extending through registering slits 1 and 8 and over the meeting edges 5 as shown in Fig; 3 which secures the cover to said pad. It will thus be seen that the pad comprises detachable layer sections a, b, c, and d on each side of the pad, said sections being detachable along the respective lines 5 and 6, and one of the portions or sections is further detachable at the line I. After the pad has been initially used, layer a is detached and-1 destroyed, thereby presenting the unused sanitary surface of section b for successive use,

and soon. It will be apparent that when the layers have been exh au sted on one side of the pad, th'e'pad may be reversed and'the' others successively used on'the other side, or each outer layer q Ia,' b b, etc.;may be detached each time the pad'is used, as-desired. It will be observed that thecovering being thinner and'more pliable and of larger dimensions than the pad 9, when the pads are positioned in connection with the respective waves the edges of the covers will tend to is so constructed and secured to the pad in such a manner as to present a plurality of layer sec tions or portions on'opposite sides of the pad, the respective outer layers adapted to be detached and discarded after each use of the pad, thereby rendering the pad at all times ready for repeated use in a sanitary condition.- g r In the case of a spiral wave a differently shaped and suitably constructed circular felt pad I I formed.- with a central opening I2 is used, and asthe hair does not come in contact with the exposed surface of the pad as in the Croquignole wave it'isonly necessary to apply the cover C to r one side of the ad as shown in Fig. 4. A rectangular blank comprising one or more sheets of paper V or other suitable material may be folded'alternate- 1y upon itself as at I3 to form a plurality of superimposed layer portions a, b, c, and d and forming the square or rectangular cover C. Each layer portion'a, b, c, and dis detachable along its respective fold line l3 similar to the layer portion of cover B. Therespective detachable portions comprising *the cover C are formed at points spaced from their ends with registering openings 7 g The edges of cover C overlie the edges of pad I l similar to cover B, except that in one direction the cover extends a substantial distance'beyond the edge of the pad and forms extension I6 adapted to protect the neck from any possibility of being burned by the metal heater or heated excess liquid. 7

The spiral wave is adapted to be used on the lower fringe of the hair, and when what is known as the cooking operation is completed the metal.

heaters for the respective waves are suspended from the persons head for a few minutes until they can be released by the operator, and therefore the extension or elongated portion protects the neck from possibility of being burned when the hair has been released from the machine and prior to the removal of the heated parts. Under conditions where the portion I6 is not desired, said portion may be severed as at H, so that the cover may conform more nearly to the sizeof the pad ll. 7

When giving the spiral wave all over the head, except the lower fringe as above described, cover C may be constructed without section IE, or said section maybe detached as desired. r

' It will be observed that while in the interest of keeping the pads clean and as an aidin easily applying the-pads and covers to the head as a unit, it is to be understood :the attaching means may be omitted, since when the hair to be waved ispassed'through the registering openings in the pad and cover, said cover is maintained in proper position with respect to the pad. 7

It is likewise to be understood that the cover may be constructed of a minimum of material ing of permanent waves in a persons hair, where, I

by the cover or the hair or scalp contacting sure face sections of the cover are discarded after each use so as to present sanitarysurfacesfor' the next use of the pad, and permitting the pad to be usedrepeatedly, said cover being so designed as to prohibit likelihood of burns from the heated parts of the machine and also adapted to'catch and prevent any excess heated liquid with which the hair may be treated from reaching and-burn ing'the, persons skin; yet one easily applied to the pad, manufacturable at a minimum of cost and efiicient for thepurposes intended.

- .Although. in practice I have found that-the form of my invention illustrated in the accompanying drawing and referred to in the above de-- scription as the preferred embodiment is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my invention will necessarily vary, I desire to emphasize that various minor changes in the number of layers, details of construction, proportion and arrangement of parts, may be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of this invention.

Having thus described my invention, what I desire protected by Letters Patent is as set forth in the following'claims:

1. In combination with a protective pad formed with an opening used in connection with the giving of permanent waves to the hair; of a sanitary covering for the pad formed from a blank folded upon itself to form V-shaped folds, the central fold forming a cavity adapted to receive said pad and provide a plurality of detachable layers on opposite sides of the pad, the layers not adding materially to the weight and thickness of the pad and functioning as heat repellants, said layers being formed with openings adapted to register with each other and the opening in the pad, the covering adapted to be maintained in proper association with the pad by the hair for the wave extending through said registering opening, whereby the outer layer on each side of the covering is adapted to be discarded after being used to present sanitary outer surfaces.

2. In combination with a felt pad or the like formed with an opening used in connection with the giving of permanent waves to the hair; of a sanitary cover adapted to prevent contact of the pad with a persons head formed with a plurality of superimposed detachable thin sheet layer sections, said layers adding no material weight and thickness to the pad and functioning as heat repellant and fluid absorbing mediums, the outer layer adapted to be detached after each use, said layer sections being formed with extension portions and having openings adapted to register with the opening in the pad and through which the hair for the wave extends, whereby a sanitary exposed surface for each repeated use of the pad is effected and protection of the skin beyond the area of the pad afiorded.
